Description
Technical field
The present invention relates to zinc electrolysis field, particularly relate to a kind of in zinc electrorefining technique for collecting the device of the cell bottom anode sludge.
Background technology
The zinc of 80% adopts hydrometallurgical processes to produce in the world at present, and the final operation of zinc wet extraction process flow process is zinc electrolysis deposition, and namely zinc is separated out in negative electrode from solution of zinc sulfate, then casts zinc ingot metal product.In zinc electrolysis deposition process, in order to extend the life-span of alloy lead anode, with the addition of a certain amount of mn ion in the electrolytic solution, these mn ions are easy to be oxidized to Manganse Dioxide on anode, form the anode sludge.Meanwhile, also there is certain foreign ion in electrolytic solution, as calcium, aluminium, magnesium, silicon etc., these ions also can form crystalline deposit with the form of composite salt, thus are deposited on cell bottom, form the anode sludge.If the anode sludge being deposited on bottom land is cleared up not in time, cathode efficiency and quality product will be affected, and therefore need to carry out periodic cleaning to electrolyzer inner anode mud.Simultaneously due in process in zinc electrolyzing, current density is higher, and single groove is comparatively large by strength of current, if adopt short circuit operation, needs to install expensive big current short circuiting switch.In order to reduce investment, zinc electrolyte tank does not generally install short circuiting switch, causes the cleaning of the zinc electrolysis anode sludge all to adopt the method for Hand scarf, and namely do not have a power failure cleaning.At present, zinc electrolysis enterprise generally adopts lays anode sludge collection tube A at bottom of electrolytic tank, the tube wall of this pipeline digs some holes, the anode sludge is made to be deposited in pipeline by pipe tap, pass through Vacuum suction pump again, adopt rubber hose to be inserted in conduit, the anode sludge is extracted out, reach the object of the cleaning anode sludge.Its structural representation is shown in Fig. 1.
The advantage of the method is, operation is simple, easy handling, and achieves the online suction cleaning of the anode sludge.But owing to there is plate crystal in the zinc electrolysis anode sludge, easily the tube wall collection hole of blocking conduit, causes segment anode mud to be difficult to enter into collection tube, forms the bottom land anode sludge and piles up, have a strong impact on zinc electrolysis economic and technical norms and quality product.In order to clear up the anode sludge of accumulation in time, current manufacturing enterprise all adopts the mode of artificial pumping board to clear up, namely the part negative plate interval in electrolyzer is extracted out, utilize the space of extracting negative electrode out, vaccum suction tube is inserted into bottom of electrolytic tank and carries out anode sludge suction.The method not only manual work intensity is large, and operating environment is poor, and operating efficiency is low, affects zinc electrolysis production capacity.
Summary of the invention
The object of the invention is the defect for the online pumping process technology of the above-mentioned zinc electrolysis anode sludge, by carrying out appropriate design to zinc electrolyte tank internal structure, and provide a kind of in zinc electrorefining technique for collecting the device of the cell bottom anode sludge.
The object of the invention is to have come by following technical solution, it mainly comprises cell body, vacuum suction apparatus, the bottom of described cell body is trapezoidal shape, the bottom of this cell body is provided with anode sludge capturing device, cell body two ends are provided with transmission rig, and anode sludge capturing device is connected with transmission rig by corrosion-resistant drag rope; Described vacuum suction apparatus is positioned at the both sides of cell body, and the vaccum suction tube in vacuum suction apparatus is inserted in the bottom of cell body, and this vaccum suction tube extracts the anode sludge by vacuum pump.
As preferably, described anode sludge capturing device adopts the insulating material such as Reinforced Polypropylene, chlorinated polyvinyl chloride, Vinylite concrete or glass reinforced plastic to make, its structure designs corresponding shape according to the trapezoidal bottom of cell body, and namely three faces of anode sludge capturing device can realize fitting with bottom of electrolytic tank.
As preferably, be provided with pulley in described transmission rig, this pulley is attached to cell body two ends, and this pulley is connected with corrosion-resistant drag rope.
Beneficial effect of the present invention is: this device is simple to operate, is easy to realize industrial applications, and operational stability is good, not only achieves the online suction of the anode sludge, and substantially increases the aspiration rates of the anode sludge, avoid the accumulation of the anode sludge; Realize process in zinc electrolyzing long-term operation, promote zinc electrolysis list groove throughput, meanwhile, reduce labor strength, improve operating environment.
